1. Temperature dependence of egg development of Dinocras cephalotes (Curtis) (three German and one Norwegian population) and Slovenian D. megacephala (Klapalek) was studied under a constant 14 : 10 light : dark photoperiod and constant temperature ranges of 4–24 °C and 4–18 °C, respectively. D. cephalotes was also incubated under seasonal field conditions; natural daylength and fluctuating temperatures had no modifying effect. 2. Both species have very similar lower threshold… Expand
The stonefly (Insecta: Plecoptera) seed bank theory: new experimental data
The perlid stonefly, Dinocras cephalotes (eunis), is the most widespread member of the family Perlidae in Europe, ranging from the south o f Italy and Spain to northern Norway, far north of theExpand
Egg Development in Dinocras Cephalotes (Plecoptera, Perlidae) at its Altitudinal Limit in Norway
Egg development of Dinocras cephalotes (Curtis) was studied in a population from the Jotunheimen Mountains of central southern Norway and the mean length of first instar nymphs increased significantly (P<0.001) with increasing egg incubation temperature. Expand
Capacity of discontinuous egg development and its importance for the geographic distribution of the warm water stenotherm, Dinocras cephalotes (Insecta: Plecoptera: Perlidae)
It is suggested that high cue temperatures required to initiate egg development in Scandinavian populations are adaptive and ensure that larvae in the Arctic hatch under favourable seasonal conditions. Expand
Life history and development of Dictyogenus fontium (Plecoptera: Perlodidae) in two thermally contrasting streams at Lunz am See, Lower Austria 1
The life history of a large stonefly, Dictyogenus fontium, was studied over several years in two streams at Lunz, Lower Austria, finding that time thereby gained was lost during delayed egg development at low temperatures in autumn and winter. Expand
Egg Development in the Stonefly Pteronarcys californica Newport (Plecoptera: Pteronarcyidae)
The placement of diapause early in embryonic development is suggested as a cause of extended recruitment of Pteronarcys californica Newport and the variety of embryonic development in Plecoptera is briefly reviewed. Expand
Life cycle, nymphal feeding and secondary production of Dinocras cephalotes (Plecoptera) in a Mediterranean river
The nymphal feeding study revealed that the main prey of these organisms are Chironomidae, Psychomyiidae and Baetidae, but some of them, usually the smallest, also had non-animal matter in their guts, mainly detritus, coarse particulate organic matter and algae, so, an onthogenetic shift in feeding was detected.

Life cycle of Dinocras cephalotes (Curtis, 1827) in Central Italy (Plecoptera, Perlidae)
The results confirm that life cycle of D. cephalotes is clearly influenced by latitude and by the related joint parameters (temperature, day lenght, etc.). Expand
Larval growth and development in the caddisfly Cheumatopsyche brevilineata under natural thermal regimes
There were highly significant regressions in the growth rates for fourth and fifth instar larvae and in development rates forFourth instars larvae against every statistical parameter of water temperature, but not in the development rate for fifth instars. Expand
Geographical variation in Japan in egg development of the mayfly,Ephoron shigae(Ephemeroptera: Polymitarcyidae)
The effect of temperature on embryonic development was compared in four populations of Ephoron shigae, including one each near the northern and southern periphery of the species range in Japan, and there was no detectable difference in the observed intraspecific variations between unisexual and bisexual populations.
